"I cannot be the one to face the fire lord. It is the avatar's destiny. One brother stealing power from another… this is not the way," Iroh wised wisely. Everyone nodded in agreement, vibing with him. Then, he shifted gears entirely. "So, Zuko, how about fighting Azula for the throne?"
"Wait, didn't you literally just say that siblings fighting each other doesn't look good?" Zuko pointed out. "You won't fight your brother, but it's okay if I fight my sister? What's up with that?"
"Ah. You have caught me in a contradiction," Iroh said calmly. As his wisdom was the source of his power, he disintegrated.
Zuko screamed in horror. The Thanosing had finally gone too far.
